Can Oblique Sliced Method Avoid Warping?

Abstract

Warping is the most important problem of costal cartilage grafts used in secondary rhinoplasties. The aim of this study is to show that costal cartilage grafts prepared with oblique sliced method (OSM), can solve the warping problem and provides successful results in both functional and aesthetic appearance. There are 42 patients who had previous nose surgery and dissatisfied with their facial appearance included in the study to perform secondary rhinoplasty with costal cartilage graft OSM technique. The outcomes of the operations were performed objectively using facial measurements and subjectively using rhinoplasty outcomes evaluation (ROE) scale, before and 12 months after the operation. The mean of total ROE score was 8.171 ± 3.285 on the pre-operative period and it was increased to 19.11 ± 3.652 where the P value was found to be <0.0001. And the post-operative 12th month period all values of nasal dorsal angulation was lower then 1° and the mean of angulation degrees was 0.224° with the minimum value 0.000° and maximum value 0.801°. The study revealed the outcome of rhinoplasty which done by OSM was statically significant both subjective patient's satisfaction and objective facial measurements. The authors suggest using of OSM in secondary rhinoplasties because the graft can be easily prepared with the desired thickness and carved into different shape without risk of warping.
